DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a plug seedling, such as a flower or vegetable seedling, which has been sowed in a plug seedling tray and grown to about 4 to 6 leaves after germination. And a temporary planting device for temporary planting in a temporary planting pot.

[0002]

2. Description of the Related Art Conventionally, a technique relating to a temporary planting device has been known. For example, as shown in FIG. In the temporary planting apparatus shown in FIG. 17, a transport mechanism is disposed on a transport table 61, on which temporary cups are randomly placed, and circulates through an elliptical conveyor 63 formed on a horizontal plane of the transport table 61. I'm moving. A plug seedling tray conveyor 50 for transferring the plug seedling tray 51 is arranged on one side of the lower part of the transfer stand 61, and the plug seedling extracting mechanism 52 arranged on the transfer stand 61 removes the plug seedlings from the plug seedling tray 51. For one row, and inserted into the temporary storage cup 53 sent below the seedling extraction mechanism 52.

In the temporary placement cup 53, one plug seedling of the plug seedling tray 51 is inserted one cup at a time. In addition, since dwarf seedlings have been generated, it is necessary to thin out the dwarf seedlings. In the sorting mechanism 62, a temporary storage cup 53 for missing or dwarf seedlings is provided in another U-shape provided inside the conveyor 63. The conveyor 56 is moved to the stock-out temporary storage cup row. A washing station 57 is arranged in the middle of the U-shaped conveyor 56, and the portion of the soil put into the inside is washed, and the temporary storage cup row 58 after cleaning is empty of the temporary planting plug seedling temporary storage cup row 59. Merges with the temporary cup, and is arranged neatly on the elliptical conveyor 63.

[0004] A temporary planting tray conveyor 54 for transporting a temporary planting tray 60 provided with a temporary planting pot 55 is disposed on the other side of the lower part of the transfer table 61. The rows of the plug seedling trays 51 into which the normal seedlings have been inserted, which have been selected by the selection mechanism 62, are thinned out and then lined up in one row after thinning out the temporary stocking cup rows, and temporarily planted plug seedling temporary stocking cup rows 59. Are arranged above the temporary planting tray 60. Above the temporary planting tray 60, the planting mechanism is used to temporarily plant the temporary planting tray 60.
The row of temporary cups after the temporary planting is the same as the temporary planting tray 60 with soil.
It is not necessary to wash it, and it joins with the temporary storage cup row 58 after the cleaning that has passed through the cleaning station 57 in the missing stock temporary storage cup row 56, and is again placed under the seedling extracting mechanism 52. It moves cyclically. The above is the structure of the conventional temporary planting device.

[0005]

However, the above prior art has the following disadvantages. That is, since the transfer path of the temporary storage cup of the transfer table 61 is configured in a plane, a wide transfer area is required. Further, within the plane, the elliptical conveyor 63 and the U-shaped conveyor 5
Since it is necessary to arrange six and two conveyors for circulating movement, a large area is required for this purpose.
Therefore, a heavy transfer table is required, and the manufacturing cost is increased. In addition, a member for supporting the carrier at a predetermined position must be rigid and strong. Further, a stock-out temporary storage cup formed by a stock-out between the rows of the plug seedling tray 51 is selected by the selection mechanism 62 and transferred to the U-shaped conveyor 56 by bypass. It is necessary to rearrange the columns 59 in a packed state, and it becomes difficult to perform this operation accurately. In addition, since the cleaning station 57 is also disposed on the transfer table 61, a space for the cleaning station 57 is also required, and the transfer table 61 becomes large and takes up space. The present invention as described above,
This is to solve the disadvantages of the prior art.
